      Question

      A train of length β€˜x’ m crosses a β€˜x + 360’ m

      long platform in 60 seconds. If the train crosses a tree in 18 seconds, then find the value of β€˜x’.
      A 270m Correct Answer Incorrect Answer
      B 250m Correct Answer Incorrect Answer
      C 300m Correct Answer Incorrect Answer
      D 210m Correct Answer Incorrect Answer
      E 330m Correct Answer Incorrect Answer

      Solution

      Speed of train = x/18 m/s So, (x + x + 360)/(x/18) = 60 2x + 360 = 10x/3 x = 270 So, the value of β€˜x’ is 270 m.
